Abstract
Although, hydrogen is a promising key solution for the effective delivery of electricity, the issue of finding materials for efficient storage has still remained a significant challenge. Due to the marvelous features of graphene and graphene-based structures, they can be one of the best candidates among all the materials. The purpose of this study was to investigate the synthesis of graphene oxide by improved hummers method and graphene by liquid phase exfoliation (LPE) technique which is safe, easy, economical, and high in quality. In addition, the prepared samples were analyzed and characterized by SEM (Scanning Electron Microscopy), TGA (Thermo Gravimetric Analysis) Setaram Labsys Evo), UV–VIS absorbance spectra, XRD (X-ray diffractometer).
Highlights
Energy demand continues to rise owning to the increasing population of the world and the rapid development of some countries that want to upgrade their living standards
Scientists are looking for alternative energy sources to replace fossil fuels such as solar, wind, hydro, tidal, geothermal, biomass etc
Some of the main graphene fabrication methods include (a) Chemical Exfoliation methods in which use strong acid with the aim of exfoliation of graphene from graphite, (b) Chemical vapor deposition (CVD) in which product is formed on a heated substrate by a chemical reaction, (c) Epitaxial growth on SiC method is carried out at high temperature, and (d) Liquid phase peeling that is safe, high quality and easy [4]
Summary
Energy demand continues to rise owning to the increasing population of the world and the rapid development of some countries that want to upgrade their living standards. Some of the main graphene fabrication methods include (a) Chemical Exfoliation methods in which use strong acid with the aim of exfoliation of graphene from graphite, (b) Chemical vapor deposition (CVD) in which product is formed on a heated substrate by a chemical reaction, (c) Epitaxial growth on SiC method is carried out at high temperature, and (d) Liquid phase peeling that is safe, high quality and easy [4]. This route allows producing graphene nanomaterials at a large-scale for applications such as nanocomposite, transparent electrode, and sensors. Two different methods such as improved hummers and liquid phase exfoliation were used to obtain graphene and graphene oxide using graphite
